I have a default Nginx install on Ubuntu 22.04 LTS inside a Docker Container using
I want /var/www/html to remain as the root but a CakePHP 4 app to be served as follows
requests to hostname.example.com as served from /var/www/html
requests to hostname.example.com/subdir are served from /var/www/tgn/webroot
This link https://serversforhackers.com/c/nginx-php-in-subdirectory is for a laravel config. But doesn’t seem to work properly with my CakePHP 4 install.
Note: See below for the problem I found using the above config
The ApacheConf default .htaccess located in webroot contains the following
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
So this is duplicated in Nginx as follows
Nginx Configuration to Serve CakePHP 4 from Sub Directory
This config is the working config!!!
The absolute_redirect value set to off stops nginx redirecting to an external URL. By default when a request is made for http://ipaddress:8080/wms it issues a redirect to http://ipaddress/wms/ which breaks my docker config. With absolue_redirect off it redirects from http://ipaddress:8080/wms => /wms/ and keeps the ipaddress:port combination correct and only issues a relative redirect

listen [::]:80 default_server;

# Add index.php to the list if you are using PHP
index index.html index.htm index.nginx-debian.html index.php;

absolute_redirect off;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
rewrite ^ /wms/ last;

Partially working
This was an attempt but in this configuration it was issuing an external redirect and redirecting to port 80 instead of the original docker port due to a problem after login with it redirecting from http://10.19.23.87:6002/wms => http://10.19.23.87/wms/

NOT working Laravel for Hackers Config Follows
This was also causing the request to be appended. By that I mean a request to
http://10.19.23.87:6002/wms/pallets/onhand would return http://10.19.23.87:6002/wms/pallets/onhand?pallets/onhand
http://10.19.23.87:6002/wms/pallets/onhand?pallets/onhand?pallets/onhand
Until it reached the URL request length limit and NGinx returned an error
